Abstract: Methods, apparatuses, and computer readable media for location measurement reporting in a wireless network are disclosed. An apparatus of a responder station (RSTA) is disclosed, the apparatus including processing circuitry configured to decode a null data packet (NDP) announce (NDPA) frame from an initiator station (ISTA), the NDPA frame including an indication of a temporary key and an identification of the RSTA. The processing circuitry further configured to decode a NDP from the ISTA, the NDP including long training fields (LTFs), the NDP received on a channel. The processing circuitry further configured to determine whether the NDP from the ISTA is consistent with the NDP being generated using a temporary key shared between the ISTA and RSTA based on a comparison of the channel estimates. The processing circuitry may be further configured to determine for authentication whether the indication of the temporary key was generated based on the temporary key.

Abstract: This disclosure describes systems, methods, and devices related to efficient poll response frame in wireless communications. A device may cause to send a multiuser location trigger frame of subtype poll to one or more initiating station devices (ISTAs) in a multi-user trigger-based range measurement during a polling phase. The device may identify a first clear to send (CTS) frame received from a first ISTA of the one or more ISTAs during the polling phase. The device may identify a second CTS frame received from a second ISTA of the one or more ISTAs during the polling phase. The device may determine the identity of a first ISTA based on information comprised in the first CTS frame received from the first ISTA. The device may determine the identity of the second ISTA based on information comprised in the second CTS frame received from the second ISTA.

Abstract: This disclosure describes systems, methods, and computer-readable media related to adaptively changing availability of neighbor awareness networking (NAN) devices for post-NAN activities. In some embodiments, a first NAN enabled device may generate a NAN service discovery frame. The first NAN enabled device may transmit the NAN service discovery frame to a plurality of NAN enabled devices during a discovery window of the NAN. A request frame from a second NAN enabled device may be received based at least in part on transmitting the NAN service discovery frame. A response frame may be transmitted to the second NAN enabled device. A second NAN service discovery frame may be generated and include an updated availability bitmap based at least in part on data received in the request frame from the second NAN enabled device. The first NAN enabled device may transmit the second NAN service discovery frame.
